Beit k'n'owngth:tt-we;l Cier'fxnrnsfljxwnnncn and- (inciten- F. Jiu-eiNvInLii,rr citizens of` the United States,` residing: at: Greenwood and I-Iillsgrove, resp'ective'ly, inithe county? of Kent and State of Rhode Island, havein vented* certain: new alii/'dz` usefulv` Improvements iii-,Cleaning-Slides for 'IhreadfBoards,y of which the following is a specification.

This invention frelatestc ar` cleaningl slide used: more particularly on" the thread hoard of alspinnin'g` machine and: thev like, and: 'the 4'object :of fthe-' invention" is to pro'- vide* such a"-cleaiding-slidehaving'.V a: body portion? comprising a' block Vwith broad,` felt# covered -bearingsurfaces ateitherjenfd, and having -an'intermediatesrecessed' portieri lo-V cated'` between these bea/ring:Y surfaces. In this recessed portion is mounted carding clothrfcrthepurposesof' collecting and roll` ing up the fly or waste deposited on# the threadlb'oard; from theT running threads, and'. also? providing? metal* guard plate adapted to extend over the edge of the thread-board to prevent the accumulated waste from being engaged and taken up by the rapidly running thread.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings;

Figure 1 is a perspective view showing the under side of my improved cleaning block or device.

Figure 2 is a longitudinal sect-ion on line 2-2 of Figure 1, looking in the direction of the arrows. v

Figure 3 is a transverse section on line 3--3 of Figure 1, showing the wire ends of the carding cloth as set in proximity to the bearing surfaces of the block or slide.

Figure 4 is a side elevation showing a portion of the spinning machine with my improved cleaning slide mounted on the thread-board thereon. l

Figure 5 is a perspective view of my improved cleaning block mounted on the thread-board of the machine.

It is found in the practical operation of a spinning machine and the like that waste in the form of lint or ily from the running threads, collects upon the threadboard of the machine, which in time works around was. snat mi: cassis:

into" engagement with,.. andi' is taken up? by the". ruiming threads-,j thereby;y making'iknots andfbunc'hes" onfA the yarnY-` and" inj itsY quality.l ToY ohviate 'this diiiicu'ltyywehavfe provided a cleaning? slide`P or. block* ofZ our improved' construction, which.l vis adapted 'to' Ybe `moved .along-V the threadrboardj; by"A the hand' of the voperatoig :to 'bunch up' and. co1? lect the waste or flyvon the thread-board and so prevent it from` coming infcontactiwith and injuring the yarn; "and thefollowing. isa vdetailed description of' one 'construction cf. our impr'ovedcleaner 'slide' by Whichth1e cleaning.: offthe A'thread-board *asf above" de; scribed-1is'accomplishe'dJ-J TvTith'; reference to the drawings; 10 des,"i ignates the body portion of our improved slide member which is preferably'formedof a block lof wood; thel same` beingrecessed near its? center. as at"A 11 h`on? its undergside leaving. broad b'eai'i nglsurfac'esf 12"" and "13 near its opposite? ends-.f Each' otr' these broad*.bearingisurfaces is vcovered"'with felt as at 14, for the purpose of engaging the loose fly or waste which has been deposited on the thread-board and rolling the same into bunches and conducting it back into the receiving space 11 between the surfaces 12 and 13. In this recessed portion 11, we have mounted carding cloth 15, the ends of the wire teeth of which are set to extend down in proximity to the surface of the running board nearly in alignment with the bearing surfaces 12 and 13 of the block, whereby when the waste is rolled by the surface 12 of the block as it is passed along the thread-board it is engaged and collected by these teeth 16 to be further rolled and retained until finally removed when the block is lifted from the thread-board after having made a passage along its surface.

In many instances thread-boards are p-rovided with end members which are hinged to the main board 17 which end members carry the thread guide members 1S, andin order that these hinges may not interfere with the operation of the cleaning slide`,we have grooved the bearing portions thereof as at 19. In still other cases where the main thread board 17 ishinged to the frame of the machine as at 20, we out away the rear portion of the slide as at 21. so as not to interfere with this second set of hinges.

In order to positively prevent the accumulated waste on the cleaning slide from coming in contact with and being picked up by the running thread, We have provided a shield plate 22 which is secured to the outer edge of the cleaning block to extend down over the ends of the hinged members 16 of the thread-board, to ride on the shank portions of the thread guides l1 and so positively prevent the Waste from Working along these guides to be finally taken up by the threads.

@ur improved cleaning slide or block is extremely simple and practical in construction and efective in its operation and by sliding the same along the thread-board of a spinning machine and the like, it will take up land retain the accumulated Waste and positively prevent the same from coming in contact With and injuring the running threads. l

rlhe foregoing description is directed solely towards the construction illustrated, but We desire it to be understood that We reserve the privilege of resorting to all the mechanical changes to Which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

vWe claim: l. A cleaning slide for a thread-board, comprising a block presenting Wide bearing surfaces at either end and provided with an intermediate recessed portion, a strip of felt covering said bearing surfaces, carding assenso cloth mounted in said recess, and a metal guard to prevent the Hy from coming in contact with the running threads, the bearing surfaces and carding cloth being suitably longitudinally recessed to permit the passage of the slide over the upstanding hinges attached to the thread-board.

2. A cleaning slide for a thread-board, comprising a block presenting Wide bearing surfaces at either end and provided With an intermediate recessed portion, felt covering said bearing surfaces, carding cloth mounted in said recess, the ends of the teeth of said carding cloth and the bearing surface of the block being substantially in the same plane.

3. A cleaning slide for a thread-board, comprising a block presenting Wide bearing surfaces at either end and provided with an intermediate recessed portion, a strip of telt covering said surfaces, carding cloth mounted in said recess, the ends of the teeth of said carding lcloth being set substantially flush with the entire bearing ysurfaces of the block, and a metal' guard having its edge extending over the edge of the thread-board to ride on t-he thread guide members to prevent Waste from being taken up by the runu ning threads.
